Specification of Letters latcnt.

Patented Oct. a, was.

Application filed April 1, 1912. Serial No. 687,691.

My invention relates to typographical composing machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to O. Mcrgenthaler, wherein circulating matrices are released from a magazine in the order in which their charac-l ters are to appear in print and then assembled in line, the composed line transferred to i the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through a distributing mechanism to the magazine from which they started.

More particularly. the invent-ion relates to the distributing mechanism, and is shown by way of example and in preferred form in connection with a machine, wherein a pllr rality of distributers are arranged in asso ciated relation to each other. However, it will beapparent that my improvements may be similarly employed in-connection with a single distributor, and that there is no limitation imposed by their present mode of illustration.

in the lilcrg'cntl'uiler patent abovc men- "tioncd, the distributing deviccs comprise rotating screws which convey the matrices alonga grooved rail or bar, from which they are released at the proper points to return them to the appropriate channels in the magazine, and my invention is herein sct forth-inconncction with that specific mechanism. Obviously, however, the principles thereof are capable of far broader application, and may be adapted to distinctlygdiffercnt stylcs of distributors, as well as to other forms of typographical machincs, such for instance as tho e which handle type or dics instead of matriccs. (lcncrally speaking, 1 dcsirc it to bc undcrstood that I do not limit myself to any spccitic form or Cll'lbOtllllitlli cxcc -t in so far as such limitations are specified in the claims.

A principal specific object of the invcntion is to arrest positively the rotating distributor screws or equivalent devices, in the event that a type or matrix, while in relation thereto, is improperly arrested, as for instance'if it becomes lodged in the entrance to a maga zinc and there resists the normal operation of the screw or similar part. The screws or equivalent members are ordinarily synchronously rotated or operated, and I pro-.

.pcse to construct them so that in the event of undue resistance or other similar derangement, this synchronism will be interrupted, thereby calling into action certain connected parts, which ordinarily run freely but which in such circumstances are thrown out of their normal relations, and as a result thereof interfere and contact with each other so as positively to arrest the further operation of the screws or other members. More spc' cifically, I provide means in the form of eccentrics, specially formed gears, or the like, mounted upon the screws 11'! such mannerthat ordinarily they clear each other, but are thrown into interfering orbits immediately when the synchronisn'l of the rotating screws is disturbed.the result of this actioninvolving their binding or contactin such manner that the screws are positively arrested and the breakage or bending of the parts or of the type or matrices is therefore avoided.

Another feature of the invention, and one whichmay be used either in connection with the devices abovc rcfcrrcd to or absolutely independently thcrcof if dcsir d, is a special means for disengaging the driving mecha nism in the event that tho opcration of the distributing devices is arrested, whether this happens because of the action of the parts already described, or in some totally differcnt manner. In other words, althoughthis feature may be employed advantageously with the means for positively arresting the screws, it is similarly applicable to any form of distributor, or other lllQtlllllllsHl, wherein it may be dcsircd to uuclutch or othcrwisc disengage the driving mcans in the cvcnt oi thc arrcst of thc driven parts.

llc'l'crring to thc drawings: Figure 1 is an end view of the distributing devices, ctc., having my invention applied thereto, partly broken away and partly in section: Fig. 2 is a vertical sectional view, taken suhstantially on tho line 2-2 in Fig. 1: Fiat 3 is a top plan vicw of the driving mechanism and disengaging devices, etc., partly broken away; Fig. 4" is an end view of a pair of screws, the connected eccentrics, etc, illustrating their normal operation when the screws are synchronously operated; Fig. 5 is a similar View, illustrating the locking and arresting action of the eccentrics when the synchronism is interrupted; Fig. 6 is a side view of the parts shown in Fig. 4; Fig. 7 is a View of a modified form, wherein gears are substituted for the eccentrics; Fig. 8 is a sectional view, taken substantially on the line- 88 in Fig. '4'; Fig. 9 is a detail View, illustrating the normal engagement 'of the gears when the screws are synchronously operated; and Fig. 10 is a similar view, illustrating the interference and locking action of the gears when the synchronism is interrupted.

Referring first to Figs. 1 to 6, the matrices X are released from the dis'tributer rail or bar X and pass into the magazine channels E in the usual manner. The mat rices are caused to travel along this rail or bar by synchronously rotated screws, also as usual, in the present instance the first screw in the upper series being designated by the reference letter A, the other screws in the upper series by the letter B, and the screws in the lower series by the letter C. The screw A. is provided with the sprocket wheel A which is actuated by the sprocket chain A", and from the screw A motion is imparted to the other screws B and C by the gearing now to be described. The screw A has a gear A which engages the gear B on the first screwB, and each screw l3 carries a gear 13 which gears B mesh into each other and constitute a train of gearing so that all of the screws B are synchronously rotated from the screw A. The screw A also has a gear A "which engages a gear C on the first lower screw C, the other screws C being also each provided with a similar gear C and all of the gears C meshing into each other and forming a train of gearing, whereby the screws U, are actuat d from the screw A in synchronism therewith and consequently also in synchronism with the screws B. It will be understood that this particular system'of gearing is uncsscntial to the invention and has been described. simply by way of example. For present purposes it is necessary merely to consider the relative operation of two synchronously actuated screws, such for instance as the screws B and C of any particular pair, the special means for imparting such synchronous operation thereto be ing immaterial and dependent upon the particular application of the invention, that is to say, whether in single series, or in a plurality of such series as in the illustrated instance.

Referring now to the first branch of the nowaoso invention it will be noted that in Figs. 1 to 6, each screw B and C of a. single pair is provided with two eccentrics fast thereon, the screw B with the oppositely located eccentrics B and B, the oppositely located eccentrics C and C It will be further noted that these pairs of eccentrics are 50 arranged that the eccentrics B and C are in one and the same plane, and that the eccentrics B and C are in another plane. It follows from this arrangement that the'eccentrics B and C and the eccentrics B and O respec tively, under normal conditions run closely together at their peripheries throughout their rotation, although not touching or interfering somewhat in the same manner as a pair of eccentri; gears. This desired and normal operation. of the parts is the one that results from the synchronous operation of'the screws B and C, and is indicated in Fig. 4. To provide for abnormal resistance that may be offered to the rotation of one of the screws, as for instance if a matrix X should become lodged in the mouth of a magazine channel E without being disengaged from the screw 0, means are afforded to permit the screw C to be retarded with relation to the screw 13, or in other Words'to interrupt their synchronism. Such yielding means may be of many different forms, but for purposes of illustration Iliave shown the driving gear 0 as loosely mounted on the screw O, and provided with a spring C connected to it and to the fixed eccentric C, the spring C being of suflicient strength to hold the loose gear G in proper relation to the screw 0 in normal operation, and contact pins ()and 0 being formed respectively on the gear C and eccentric G to limit the action of the spring and locate the gear in operative position in ordinary circumstances. In the previously mentioned event of undue resistance to the rotation of the screw, caused for instance by the accidental lodgmentof a matrix in a channel mouth, the spring C yields and permits the movement of the gear C with relation to the sci-cg C; andthe synchronism of the screws an d C is thereby interrupted. This abnormal mode of operation is illustrated in Fig. 5 and-results in the interruption of the'ordinary freeaction ot' the eccentrics. Theirorbits are now caused to intersect, whereupon one or the other of the'eocentrics T3 and C", or B and C, will contact and bind, and due to their rigid mounting upon the respective screws, the further rotation of the latter .Wlll be promptly and positively arrested.

thereby obviatingihc liability to breakage or bending ofthe parts.

It will be apparent that many equivalent means Wlll be comprised and the screw C with with each other,'-by analogy,

within the spirit intense I I of my invention. For instance, in Figs. 7 to 10, It have illustrated a form wherein the pairs of eccentrics are dispensed with, and in lieu thereof the screws A and C are provided with intermeshing gears C the teeth C of which are so arranged and spaced that in normal operation, (see Fig. 9), and so long as the screws are rotated in unison, the teeth will engage between and clear each other without disturbing or interfering with the normal rotation of the screws. It-will be understood that the screws C are driven in substantially the same manner as before described, namely, by pinions which are normally held in operative position by means which yield in the event of undue strain. llt will be seen that the teeth C of the gears C are spaced at unequal distances thereon, and that in the event of a screw being retarded, its gear C will be relatively displaced with reference to the neighboring gear (1 with which it normally engages. In the event that the synchronisin is interrupted, this gear C will therefore lag behind, thus disturbing the normal meshing of the gears (see Fig. 10), and due to their peculiar spacing, the teeth C of the arrested gear will engage on the periphery of the teeth of the neighboring gear, which continues to rotate, instead of in the spaccs'between them. T his peripheral contact of the teeth obviously arrests the rotation ofthe screws in the same manner as previously described.

Turning now th the second branch of my invention, and referring to Figs. 1, 2 and 3 of the, drawings, this comprises means whereby the arrest of the distributing mechanism automatically disengages the driving devices. As previously stated, while this mechanism may be and is advantageously employed in connection with the before-descrlbed means for arresting the distributor screws, it is similarly available in otherrelations and in cases where it may be desired automatically to throw the power out of action in the event of the undue resistance of some driven part. lhe sprocket chain A which imparts motion to the sprocket wheel A is operated by a sprocket wheel D mounted upon the rotating sleeve 1). The wheel D formed with a cylindrical extension D interiorly screw threaded zit D to engage a corresponding screw thread upon the sleeve D The parts D and D are held in normal operative relation to each other by the torsional. spiral spring D connccted thereto, the turning effect of the spring being limited by the engagement of a pin D on the extension D with a pin I) on the sleeve D and a second pin 13' being mounted upon the sleeve D to limit 1"lti moveme it in the tion, but in the event of resistance being ofiered through the sprocket chad; A to the wheel D, the spring D yield s4 and permits the sleeve D to rotate relatively to the wheel D and its extension D and due to the screw thread connection of the parts, this relative rotation results also in a longitudinal relative movement of the wheel D and extension D (in the sleeve D It is. this lateral movement of the wheel and its extension which is availed of to disconnect the driving mechanism. Power is imparted by a belt or in any suitable manner to the driving wheel F mounted upon the extension sleeve F on the stud or spindle F and within the previously mentioned sleeve D Rotation is imparted to the sleeve D by, the friction member or extension D thereon, which is normally pressed into engagement with the driving wheel F by the spring 1).

The sleeve 1) is also provided with the cam D formed with laterally extending cam surfaces, whereby the sleeve may be moved longitudinally against the force of the spring D and in such manner as to break the connection of the friction member D with the driving wheel F. ,The means for engaging the lateral camisurfaces of the cam D are carried by the stop member H, pivoted at H in such manner that, unless restrained, it drops forward and projects its finger H into the path of the cam. When the machine is operating in the ordinary manner, the stop member H is held in its uppermost or inactive position, it being retained therein by the engagement of its lateral arm H with the pivoted trigger G. The trigger G is normally pressed forward by a spring G so as to bring its upper portion in front of the arm H and its lower portion against and in contact with the extension D of the sprocket wheel D.

The operation of the parts will now be readily apparent. If the wheel D is arrested for any reason, as for instance by the sprocket chain A in the manner previously described. the continued rotation of the sleeve D due to the screw thread connection D, eil'ccts the lateral shifting of the wheel D and its cylindrical portion D and the latter acting upon the trigger G withdraws its support from the arm H of the stop member H, which consequently moves forward and projects the finger H into the path of the cam 1 and due to the continued rotation of the sleeve D it is moved longitudinally by the cam against the force of the spring D and thereby breaks the onerative connection of its friction memberD with the driving wheel F, and the parts come to rest. 5
